I used the Long Cut IMR 7828 because that is what I have in my inventory. SC should give the same velocity.
Hey "shinbone" would very much like to hear about your results with Retumbo & the Barnes 120gr TSX as I had poor accuracy results with that powder in my EW.. Like you said nice to hear about results from other 264 shooters. As a bit of information I have another 264 1/9 twist that shoots the Barnes mono's with the slower powders like Retumbo wit excellent accuracy.
